The diagnosis of leukemia should not be based solely on the number of white blood cells, but should be based on a comprehensive evaluation of the patient’s bone marrow, clinical symptoms and other indicators, so that the diagnosis of leukemia can be confirmed by a professional doctor. Leukemia patients not only show abnormalities in the quantity of white blood cells, but also in their “quality”, which is more important in the diagnosis. Specifically, a certain percentage of “primitive” or “naive” cells may be found in the peripheral blood and bone marrow.
Leukemia patients generally have significantly elevated white blood cells, some of which can be over 50X10^9/L or even over 100X10^9/L. A small number of leukemia patients may have significantly low white blood cells. Usually in advanced stages of leukemia, bone marrow hematopoiesis is suppressed, which leads to a significant decrease in granulocyte, red blood cell and megakaryocyte proliferation. In addition, leukocytes may also decrease when the body is affected by viral infections, typhoid fever, fever, etc. Therefore, leukemia cannot be diagnosed solely on the basis of leukocyte indicators. If a patient has an abnormal blood count combined with fever and other symptoms, a comprehensive evaluation by a medical professional is required to diagnose leukemia.
Therefore, patients with elevated leukocytes should not be overly worried about leukemia, but should maintain a good attitude and actively seek medical advice.
